Express Concrete delivers ready mix concrete to Lewisham (SE13) from our Erith production plant — eight miles by road via the South Circular or the Blackwall Tunnel approach, usually thirty to forty minutes outside peak. SE13 sits inside our south-east London catchment and we have been the family-run choice for Lewisham foundations, basement pours, driveway works and small commercial slabs since the 1980s.
Every Lewisham load is batched at Erith to a BS 8500 mix design and arrives with a printed delivery ticket recording the mix design, batch time, water-cement ratio and plant of origin. That documentation matters in SE13 because a high proportion of Lewisham work is foundation pours on London clay where building control or your insurer may want primary evidence of what was poured. Our QSRMC accreditation back every load, and the Our Promise page sets out the published service standards.
Plant manager Oliver Wilson runs the Erith yard and is the person who answers the phone when you order. He has been routing trucks to Lewisham foundations for years and knows which streets take an 8 m³ wagon and which need a 4 m³ mini-mix. Use the concrete calculator to estimate volume or read about the Erith operation on the plant page.
Lewisham’s mix profile is dominated by foundation work on London clay — different from a sandier-soil borough where the foundation grade can be lower. We supply the full BS 8500 range to SE13 from the Erith plant. Our concrete strength classes guide covers each grade in detail.
For most SE13 domestic foundations, Oliver will recommend C20/Gen 3 with polypropylene fibre — the C20 strength carries the load, the fibre handles surface micro-cracking. For two-storey extensions or point-load footings, step up to C25/30. Composition queries are covered in our aggregates and sand guide.
Order before 11am for same-day delivery on most Lewisham jobs. The Erith-to-Lewisham drive is eight miles, typically thirty to forty minutes outside peak via the South Circular or the Blackwall Tunnel approach (Oliver picks the cleaner route on the day). Continuous pours of thirty cubic metres or more need 48 hours’ notice so we can sequence trucks back-to-back.
Most SE13 streets take an 8 m³ wagon, which is the most economical load for any pour over four cubic metres. The older terraces around Lewisham High Street and parts of Hither Green sometimes need a 4 m³ mini-mix instead — tell us the postcode at quote time.

Lewisham, like most of inner south-east London, sits on London Clay — a heavy, plastic clay subsoil that swells and shrinks with seasonal moisture. For domestic strip and trench-fill foundations, that means the concrete has to bridge a moving ground rather than rest on a stable base. The grade you specify and the consistency of every load matter more in SE13 than they do on a sandier foundation in, say, Surrey.
Our standard recommendation for Lewisham trench-fill is C20/Gen 3 with polypropylene fibre — the C20 strength carries the load, the fibre handles the micro-crack risk that plastic clay heave creates over the first two winters. For two-storey extensions or load-bearing point footings, step up to C25/30 with steel reinforcement. We will not over-spec your job to upsell you, but we will not let you under-spec it either — if your engineer has marked C25 on the drawings, we will not quote you for a cheaper grade.
The other clay-soil factor is workability. London clay foundations often have water collecting at the base of the trench (especially after rain) and the concrete needs to displace it cleanly without segregating. We default to a slump of around 100 mm for SE13 trench-fill — high enough to flow into the corners, low enough that the cement does not wash out. If the forecast for your pour day is wet or cold, ask Oliver about a retarder admixture; we can extend the workability window from ninety minutes to around two hours. See can you pour concrete in winter for the seasonal version of this conversation.
Same-day on most orders before 11am. Erith-to-Lewisham is thirty to forty minutes off-peak.
Most domestic strip and trench-fill on London clay use C20/Gen 3 with polypropylene fibre. Two-storey or point-load footings step up to C25/30. See ready mix concrete for foundations.
Yes — we default to a slump of around 100 mm for SE13 trench-fill, which displaces standing water cleanly without segregating. If the forecast is wet, ask about a retarder admixture.
Yes. Most SE13 basement slabs use C30/37 with reinforcement. We supply with fibre or steel mesh as the engineer specifies.
0.5 m³. Short-load surcharge applies — Oliver at Erith will quote on enquiry.
On the wider residential roads, yes. On the older terraces around Lewisham High Street and Hither Green, sometimes not — we will run two 4 m³ mini-mix loads instead.
Yes. Erith plant supplies GGBS-blended low-carbon mixes alongside the standard range. See low carbon concrete.
